Volume Discounts for ABN / Account holders -
Premium quality mild steel CD (Capacitor Discharge) weld studs, threaded M4 x 20mm, supplied in convenient packs of 100 — ideal for trade, industrial, and workshop use.
Product Overview
These M4 x 20mm CD studs are precision-manufactured from durable mild steel, designed specifically for use with capacitor discharge (CD) stud welding equipment. CD welding is a fast, clean, and highly efficient method of fusing a threaded stud directly onto a metal surface without pre-drilling, making these studs a popular choice across fabrication, construction, automotive, signage, and general metalworking applications.
Key Features
- Material: High-quality mild steel for excellent strength, weldability, and corrosion resistance when finished/coated as required
- Thread size: M4 (metric) — a versatile, widely-used thread size suited to lighter-duty fixing and mounting applications
- Length: 20mm, providing ample stand-off for brackets, panels, cable trays, insulation pins, nameplates, and fittings
- Pack quantity: 100 studs per pack — ideal for bulk trade use, reducing reorder frequency and cost per unit
- Compatibility: Designed for use with CD (Capacitor Discharge) stud welding guns for a fast, single-sided weld with no distortion or marking on the reverse side of the base material
Common Applications
- Attaching name plates, signage, and labels to metal surfaces
- Fixing insulation pins and cable trays in construction and HVAC installations
- Automotive panel repair and trim fixing
- General fabrication and sheet metal work
- Mounting brackets, guards, and fittings without through-drilling
Why Choose CD Studs?
Capacitor discharge stud welding offers a stronger, cleaner, and more efficient alternative to traditional drilling and bolting methods. Because the weld is completed in a fraction of a second, there's no heat distortion, no visible marking on the opposite face, and no need for pre-drilled holes — saving time and labour on every job. Supplying these mild steel M4 x 20mm studs in a bulk pack of 100 ensures tradespeople, fabricators, and manufacturers always have stock on hand for continuous production runs or large-scale installations.
